Application filed September 20, 1921.

To all whom it may concern:

Be it known that I, TnonAs J. CHARON, a citizen of the United States,residing at Park River, in the county of Walsh and State of NorthDakota, have invented certain new and useful Improvements in PowerAttachments for Automobiles, of which the following is a specification.

This iiwention relates to a power attachment for use in connection withmotor vehicles.

The primary object of the invention is the provision of a powermechanism for operation by the driven wheels of a motor vehicle, wherebypower can be transmitted to various desired places in an effective andfacile manner, for performing WOZC'l-I.

A. further object of the invention is the provision of a device of theabove described character, including an improved means for mounting anddismounting of the motor driven wheels of a vehicle thereon.

Other objects and advantages will be apparent during the course of thefollowing detailed description.

In the accompanying drawings forming a part of this specification, andin which similar ref rence characters designate corresponding partsthroughout the several views.

Figure 1 is a side elevation of the improved power attachment showingthe motor vehicle as used in connection therewith.

Figure 2 is a rear elevation of'the improved power attachment, showingthe motor vehicle in operative engagement therewith.

Figure 3 is a plan view of the improved power attachment.

Figure- 1- is a cross sectional view taken on the line 1 d of Figure 3.

Figure 5 is a. cross sectional view, taken on the line 5-5 of Figure 3.

Figure 6 is an enlarged and fragmentary view showing the operativeconnection of several details of the power attachment.

In the drawings, wherein for the purpose of illustration is shown apreferred embodiment of my invention, the letter A designates a motorvehicle of any approved type, for use in connection with the power mechanism B. The power mechanism B preferably includes the runway structureC; supporting frame D; driven mechanism E; and means F to assist indisplacement of the motor vehicle from the means E as desired.

Specification of Letters Patent.

Patented A11 1, 192%.

Serial No. 501,992.

The motor vehicle A may of course, be of any preferred construction,including the forward axle structure 10; and the rear axle structure 11;in which is included the driven vehicle wheels 12; and the enlargeddifferential casing 14.

The runway C comprises the tread boards 17 and 18, for receiving thewheels of a motor vehicle, said tread ways 17 and 18 each having avertical support 'post- 19 at the upper end thereof, which are connectedby horizontal bracing planks 20 to the lower end of each of saidtreadways. A suitable cross brace or connecting member 21 may be usedfor spaced connection of the tread ways 17 and 18 to conform to thewheel gauge of the motor vehicle.

The frame D is substantially rectangular in formation, including aforward rail member 22; a rear rail member 23; and the side rails 24:.Supporting standards 25 of any approved type, are provided as part ofthe frame means D for suspending the rails 22, 23, and 24, and may beconnected in pairs as by bolts 26 to the outer surfaces of each of theside rails 2 1. A pair of intermediate bracing rails 27 and 28, inparallel all '11- went with the side rails 24:, are provi ed centrallyof the frame D in spaced relation and connected to the forward and rearmembers 22 and 23. A rail 29 is provided intermediate the centrallypositioned rail 27 and its nearest side rail 24, and in parallelrelation to said rail 27 and. side rail 24:. Similarly, a rail 30 isprovided intermediate the other centrally positioned rail 28 and itsnearest side rail 24, and in parallel relation to said rails. It ispreferred, that all of the rails forming the frame. D be in the sameplane, to provide a simple and durable structure.

Referring now to the driven mechanism E, the same preferably includes aforward shaft 35, mounted. parallel of the forward member 22 andadjacent the same, the bearing: boxes 36 being" provided upon the sideails 24, and the bearing; boxes 87 being provided upon each of themembers 29 and 30, for rotatably receiving the shaft 85. l Vheels 38 arekeyed or rigidly fixed to the shaft 35, and positioned in the spacesintermediate the supporting rails 29 and 30 and their respective siderails 24; and in such spaced relation that said wheels 38 will conformto the gauge of said vehicle wheels 12.

A second shaft 40 is provided for rotation with respect to the frame B,the same including a pair of journal boxes or bearings ll and 1-2 foruse upon the bracing rails 29 and 30'respectively. A pair of bearingboxes set are provided in connection with the shaft and for detachablemounting upon the side rails 24. It is preferred that the shaft 40 beoscillatively mounted upon the frame D, and connected to the rotatableshaft 35 as a center. .To this end, band metal straps 46 are looped at4'? upon one end for bearing upon the shaft 34, and extending tobe'connected tora bolt 4S,which mountsthe cap l9 to the base 50 of eachof the bearing structures 4:1 and 42. Driven wheels 51: similar to thewheels 38 are provided, for fixed mounting upon the shaft 40, andintermediate the space: provided by the membersv29 and 30 and theirrespective side'rails 24s, to

conform to-the gauge offthe vehicle wheels 12. It canithus beseenthat-the; entire shaft 10 isoscillatively mounted uponthe frame B aboutthe shaft 35as a; center v; the bearing boxes 1.1, 412. and 4A:cooperating'in detachable manner upon the supporting v frame D to effectsuch result. In; order to prevent axial movement of the shaft 4L0,whereby the various bearing boxes of: the same might slip off of theframe D, bolts, 53 maylbe' providedupon the various bearing boxes of theaxle 40, which are much greaterinlength than the thickness of bearingboxes of said shaft 4E0, in order that an end 54 may project into asocket 55 of any of the rails 24, 2 7 or 28uponpwhich-said bearing boxis mounted.

The means F to facilitate removal of the motor vehicle A from themechanism E is principally formed of the lever 58; which is bifurcatedat one end to providethespaced stems 59 and 60, having the outturnedends 61 for engagement with; suitable bearing members 62Wl1l0l1 arepositioned upon the centrally spaced? rails 27 a and 28 The lever 58hasits pivotal mounting in, the bearings that the driven wheelsl2thereof, may each;

engage a wheel 38 and; 51 of the shafts and 40, and in the mannerillustrated in Figures 1 and 2 ofthe-drawings. Thus the wheels 12 willrest in: engagement with the driven mechanism E. Cables 63 and 64 aremounted;uponthe-forward rail 22, of, frame D, the same preferablybeingflexiblechains and. extend forwardly in: cross manner; to

members 65 are provided, the same being.

hingedly connected at 66 to theinside surfacesof each of the railmembers 29 and 80. Each brace member 65 includes the portion 67 which ishingedly connected as aforesaid at 66; and an adjustable portion 68,Which is detachably mounted by a; turn buckle structure 69 to a screwthreaded end of the portion=67.v End seats 70 are provided upon theextreme end of each of the sections 68. and are adapted forengagingagainst the axle housing 13. The adjustability of the arms 65hasbeen provided in order to lengthen or shorten thesame in accordance withthe type of vehicle used. The use of these brace arms 65 isobvious andintheir ordinary position will be inclined inwardly from theirsupporting rails to be in engagement at their seating ends 70 with thedifferential casin 14 to prevent lateral sway of the vehicle, if

when the same is in operation. Suitable.

frame D to the axle housing 13, in order to prevent too much vibrationof the. vehicle wheels 12 upon the mechanism When the wheels 12 arepositioned as above described, in engagement with the wheels 38-and5lof, the mechanism E and the motor of the vehicle A is operated to drivethe wheels 12, said wheels 12; will drive the shafts 35 and 40 as isobvious.

In order to provide a uniform driving ratio between the shafts 35 and40, a belt 72 is provided for driving connection over the pulleys 73 and7 t upon the shafts 35 and 40 respectively. q

When it is desired to remove the vehicleA from the power attachment Ethe lever 58 is brought into play; The free end thereof may be manuallyraised or jacked up, in order that the rear shaft 40 may beoseillated inmanner above described, thus raising the rear end of the vehicle A.Whena sufficient tilt has been given: the vehicle A, the wheels 12thereof will ride easily: over the forward wheels 38, with which theyare in, engagement, whereby thevehicle Amay berun over the treadways 17and 18, and. after disconmotion of the flexiblevcables 63fand 64 Variouschanges in the shape, size 1 and arrangement of parts, may be made. tothe fornr of the invention herein shown and described, without departingfrom, the spirit (of the invention CIT-the scope of the claims.
